She is now 1 and a half years old. This has been going on for about a week. After this happened, I tried giving her a different kind of guinea pig food and she still won't eat. She loves carrots and alfalfa, but she will not eat them. I am worried that she might starve to death. I will try to get her to a vet, but her cage is pretty big and it won't really fit in the car. I could get a smaller cardboard box to put her in while she's in the car.
